Abstract CORDIC (Coordinate Rotation Digital Computer) is an iterative algorithm for the calculation of a two-dimensional vector in circular, linear or hyperbolic coordinate systems. This paper presents a survey of known CORDIC algorithms and architectures for the rotation and vectoring mode in the circular cordinate system. In addition an implementation of the differential CORDIC algorithm in VHDL has been done. The implementation is designed to keep the fast timing and throughput characteristic known for on-line redundant arithmetic..

Undersökningens syfte är att undersöka huruvida det finns ett samband mellan traditionella könsnormer samt inställningen till det egna landets familjepolitik, och landets totala fertilitetsnivå. Uppsatsen har en kvantitativ ansats med analyser baserade på data från European Social Survey samt Eurostat och undersöker 26 europeiska länder. Den teoretiska bakgrunden belyser hur mönstret i de totala fertilitetsnivåerna har förändrats till de nivåer som uppvisas i Europa idag. Vidare beskrivs hur könsrollsattityder och familjepolicys kan kopplas till födelsetal. Av den teoretiska bakgrunden framkommer vikten av att kunna kombinera barn med förvärvsarbete som en nyckelaspekt.

Overdue cleanings have for a long time been an important topic of discussion within the forestry sector. When stands that have not been pre-commercially thinned are reaching the level of commercial thinning, many problems occur in terms of decision-making and economical outcomes. These types of stands are commonly known as conflict-stands. The work was carried out partly as an interview survey towards representatives from the forest sector and the energy sector, partly as a case study of conflict-stands situated in Böksholm, north of Växjö and in Tönnersjö east of Halmstad. The criteria for the studied stands were that they had to be dominated by Norway spruce and be in a severe status of ?conflict?. The aim of the interview was to get an overview of the situation today, and also analyse trends in terms of conflict stands.

Denna studie ämnar undersöka skillnaden i osäkra anställningar mellan unga kvinnor och män i 14 Europeiska länder dels på landspecifik nivå samt indelat i välfärdsregimer. Underlaget för studien kommer ifrån European Social Survey från åren 2010 och 2012. För analysen har logistisk regressionsanalys tillämpats i statistikprogrammet SPSS. Genom ett uppslag i tidigare forskning och teori om faktorer på både individ- och institutionsnivå formulerades två hypoteser: Att kvinnor i större utsträckning än män innehar osäkra anställningar samt att den största skillnaden skulle gå att urskönja i den konservativa välfärdsregimen. I ett inledande skede vid kontroll för enbart kön tenderade kvinnor i den socialdemokratiska välfärdsregimen att ha en större sannolikhet till en osäker anställning.

The purpose of this investigation was to study what students in in the first year of the social science program in high school think about the guidance they had access to during their time at primary school. This is to ensure that it the guidance students are entitled to and contribute to the development of the business. The survey was conducted at two different high schools in southern Sweden. A total of 57 students participated in the survey. The results show that 46 and 29 percent of students at the two schools did not feel they had the information they needed for their upper secondary school The results proving what previous research reached that students selection process can lead to stress and uncertainty associated with the choice to high school. The results of the present study showed that girls in particular have high standards for themselves and experience stress and anxiety associated with their selection to a greater extent than boys.

The purpose of the study is to examine how the teachers in second grade use SMART Board and compare two schools.The process I used was qualitative interviews and classrooms observations. Previous studies shows how widely SMART Board is used in classrooms, and this has also been shown in my study. The study shows how differently SMART Board is used in the classrooms, and how important education in the technology of SMART Board is to achieve in the classroom. The final discussion clearly shows similarities and differences in the use of SMART Board in different classrooms and also the teachers? thoughts about SMART Board as a tool.A central aspect in the use of SMART Board shows how important the basic education in SMART Board is.

Cassava (Manihot esculenta Crantz) is a root crop that plays an important role in many households in Africa. It is sometimes called ?Africa´s food insurance?. The advantages with the crop are that cassava is drought-resistant and it can grow in a semi-dry land. It is a perennial crop and does not require much labor.

Urban forests are important for people to get at break and be able to relax in a stressful world. Several studies show that we feel better through being out in the forest and historically this was the normal environment for us. As a result of population growth and urbanization we tend to spend less time in nature nowadays than before. Due to this development urban forests have become a central role in our society as a place where people can fulfill their needs and interests. The management of the urban forest is therefore important, especially for municipalities that own forest which is supposed to be of benefit to local residents.Falköpings municipality owns approximately 260 hectares of forest in the popular and most visited recreational area along Mösseberg?s southern slope.

This paper is focuses on trade between eastern Blekinge and the other side of the Baltic Sea during the Viking Age. There are scarce tracks of trade in the area but one place, Skällenäs, isdifferent. Here a treasure has been found with coins from England and Germany and some of the place names are here probably connected with places on the other side of the Baltic.This discovery can be an indication of trade but the paper should be seen as a first investigation and could be the basis of a more extensive survey..

The main purpose of this study was to examine own and social influence on perfectionismwith individual athletes. The participants (n= 96) of this study represented ten different sportsand their ages was between 15 and 44. An interview with four of the participant wasconducted. The instruments used for this study was the Positive and Negative PerfectionismScale (Terry-Short et al., 1995) and for the interviews questions was based on own and socialinfluence. The results showed that there was a relationship between positive perfectionismand own influence, negative perfectionism and own influence, negative perfectionism andsocial influence.

Do the principals who have the pedagogical responsibility of the school find reading comprehension important? This is the underpinning of my thesis for the special teacher-training program. The survey was conducted through interviews with two principals. The results show that they believe reading comprehension is important but it has not been given priority in the organization. The essay could form the basis for further research into reading habits, home environment influences and other factors that may contribute to improve reading comprehension performance..

WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad.   Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.

The main purpose with this study was to get an insight in how to best be able to help children with language difficulties, and learn to see those who are in need of extra help and attention.The study is the result of three separate interviews with a speech therapist, a preschool teacher, and a teacher for children with special needs. The other information that my study is built on comes from books.The answers that I got from the interviews questions, have I built my discussions from.Since I only have done three interviews, can´t I do any general conclusions, from my findings.The answers that I got shows that it`s not always the same answers from the speech therapist, preschool teacher and the teacher for children with special needs, are the same. But most of the answers had a similar conclusion. The most important finding in my study, which also the literature agrees with, is that. It´s always important to read out loud to the children.Keywords: language difficulties, exertion, learning to speech and communication..

The sample consists of all land funds for China and Russia has found more than 10 years on the stock market.Results and Conclusion: The survey shows that China funds will generate better in decline than Russia Funds in both return and risk-adjusted Sharpe ratio. Because the China funds had better risk diversification and its holdings spread across different industry area while Russia funds is more directed towards oil and gas industry.

Managers operating within the dynamic society of today are said to rely on intuition when effective and quick decisions are to be made. This skill or phenomenon has aroused an interest within the academic world of management whom has explored intuition, its relation to decision making and its influencing factors, especially in the private sector. Intuitive decision making is however not isolated solely to this sector but also involved in decision making associated to the public sector. Therefore, the aim of the thesis is to investigate whether managers at the hospital Akademiska in Uppsala involve intuition in decision making and to what extent the factors time, amount of information, individual experience and decision complexity influence the intuition.The theoretical framework includes academic research regarding how intuition and rationality affect decisions, the concept of intuition and factors influencing the intuitiveness of decision making. Furthermore the theoretical discussion explores intuition connected to leadership, negative aspects of intuitive decisions and a comparison between different factors that separates public and private sector in terms of decision making.
